A Middlesex County grand jury on Friday indicted Dotro on five charges of attempted murder and charges of aggravated arson.

Dotro also was charged with criminal mischief, unlawful possession of a destructive device used to set the fire, hindering his apprehension by providing false information to investigators, and retaliation for past official action of the police captain.

Dotro has been accused of purchasing marijuana while in uniform, conspiring to sell the drug, slashing a woman's tires, illegally accessing police records for personal use and carrying two prohibited weapons — brass knuckles and blackjack — in his police duty bag.

He was arrested three days after the fire was set at the home of Capt. Mark Anderko on May 20, 2013. Anderko, his wife, two children and 92-year-old mother were home but were not injured.

In a separate case, two other Edison police officers — Victor E. Aravena, 42, and William H. Gesell, 45, both of Edison — are facing charges of conspiring with Dotro to retaliate against a North Brunswick police officer who had arrested another individual on a drunken-driving charge.

The charges against the three officers are part of a series of criminal allegations, convictions and internal strife in Edison's police department dating back generations.

The Township Council last month adopted policies aimed at eliminating personnel hiring and promotion controversies.
